干旱冷凉区山杏育苗技术

Armeniaca Sibirica Seedling Raising Technique in Arid and Cold Area

山杏作为生态防护林、退耕还林工程中主要的经济林树种,对土壤条件要求不严苛,其抗寒、耐低温、耐旱、抗盐碱性都较强,在海拔200~2200 m、绝对最低温底-40℃以上的丘陵、草原、荒山、沙荒地、水土流失地等造林地区均可栽植。为提高干旱区山杏育苗出圃率及造林成活率,从圃地准备、种子处理、播种、播后管理、苗木出圃和有害生物防治等几个方面详细介绍了山杏的育苗技术,为山杏适生区的苗木种植者提供参考。

As the main economic tree in ecological protection forest and returning farmland to forest project,Armeniaca sibirica has no strict requirements on soil conditions.It has strong cold resistance,low temperature resistance,drought resistance,salt and alkali resistance.It can be planted in hilly,grassland,barren hills,sandy wasteland,soil erosion and other afforestation areas with an altitude of 200~2 200 m and an absolute minimum temperature of-40 ℃ or more.In order to improve the seedling emergence rate and afforestation survival rate of Armeniaca sibirica in arid area,the seedling raising technology of Armeniaca sibirica was introduced in detail from the aspects of nursery preparation,seed treatment,sowing,post-sowing management,seedling emergence and pest control,so as to provide reference for seedling growers in suitable areas of Armeniaca sibirica.
